If your activation / registration was successful, you will get a message that says, "Thank you for registering FileViewPro".

FileViewPro will now be registered - all program features are now unlocked!

Helpful Tip (if having problems):

If you are MANUALLY (typing the license key yourself), please be sure not to confuse "1" (number one) with "I" (letter "i" - eye), or "0" (number zero) with "O" (letter "o" - oh). These are often confused and can cause your license key to be denied.
